A muscle hardness meter which measures the hardness of a muscle tissue of the living organism comprises an auxiliary part (26) which is made to abut to the vicinity of a living organism section to be measured and applies a pressure to the vicinity of the section to be measured, an abutting part (40) which is made to abut to the section to be measured and applies a pressure to the section to be measured, a first pressure sensor (54) which measures pressures which are applied respectively from the section to be measured and the vicinity to the abutting part (40) and the auxiliary part (26) and outputs a first measurement result, a second pressure sensor (53) which measures the pressure applied from the section to be measured to the abutting part (40) and outputs a second measurement result, a notifying part (6) which notifies the second measurement result, and a control part which judges whether the first measurement result has reached a reference pressure value inputted previously and makes the notifying part notify the second measurement result obtained in the case where it is judged that the first measurement result has reached the reference pressure value.La présente invention concerne un dispositif de mesure de dureté du muscle qui mesure la dureté dun tissu musculaire dun organisme vivant et qui comprend : une partie auxiliaire (26) conçue de manière à venir se coller à proximité de la partie de lorganisme vivant à mesurer et qui exerce une pression à proximité de la partie à mesurer une partie daboutement (40) conçue pour venir se coller à la partie à mesurer et appliquer une pression sur la partie à mesurer un premier capteur de pression (54) qui mesure les pressions exercées respectivement depuis la partie à mesurer et sa proximité sur la partie daboutement (40) et la partie auxiliaire (26) et sort un premier résultat de mesure un second capteur de pression (53) qui mesure la pression exercée depuis la partie à mesurer sur la partie daboutement (40) et sor
